CAPE SABLE 89 



crenatus, so nearly like the Cuban form of the 

 species that an expert could not separate them. 

 The latter species is also found at Flamingo and 

 again near Coot Bay and its adjacent hammocks, 

 but from some of these the shells have a different 

 marking. The peculiar "black snail" occurs on 

 Key Vaca, at Middle Cape and Chokoloskee but 

 has not, so far as I know, been obtained in any 

 other localities. Usually only a single species or 

 subspecies of Liguus is found in any of these 

 hammocks, but why all other forms but one are 

 excluded we do not know. 



I had been warned repeatedly that anyone who 

 explored the Cape Sable or south shore regions 

 hazarded his life by reason of many rattlesnakes. 

 My warning included many of the keys which were 

 supposedly infested with them. In many years 

 of cruising and tramping over the lower part of 

 the State I had never met a living rattler or even a 

 water moccasin, and I had concluded that the 

 snake stories were largely myths. In the late 

 autumn of 1916, in company with Dr. Small and 

 my neighbors Victor Soar and Paul Matthaus, I 

 visited the Cape Sable region, tramping from 

 Flamingo to the cape across the interior prairie.
